While the population of massive stars is rather well studied, the associated low-mass stellar population was largely unknown up to now. The near-infrared study in this paper builds on the results of the Chandra Carina Complex Project, that detected 14368 X-ray sources in the 1.4deg^2^ survey region, an automatic source classification study that classified 10714 of these X-ray sources as very likely young stars in Carina, and an analysis of the clustering properties of the X-ray-selected Carina members. In order to determine physical properties of the X-ray-selected stars, most of which were previously unstudied, we used HAWK-I at the ESO Very Large Telescope to conduct a very deep near-IR survey with subarcsecond angular resolution, covering an area of about 1280arcmin^2^. The HAWK-I images reveal more than 600000 individual infrared sources, whereby objects as faint as J~23, H~22, and Ks~21 are detected at signal-to-noise ratio (S/N)>=3. While less than half of the Chandra X-ray sources have counterparts in the Two Micron All Sky Survey catalog, the ~5mag deeper HAWK-I data reveal infrared counterparts to 6636 (=88.8%) of the 7472 Chandra X-ray sources in the HAWK-I field. We analyze near-infrared color-color and color-magnitude diagrams to derive information about the extinctions, infrared excesses (as tracers for circumstellar disks), ages, and masses of the X-ray-selected objects.2011ApJS..194...10Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJS/194/14 : A Pan-Carina YSO catalog (Broos+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/10https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/10/table1 (Near-infrared magnitudes for the 7472 Chandra X-ray sources in the area of the HAWK-I mosaic)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/10/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/10/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/10/table1?GETtext/xml+votable180.050000true160.640755-59.568031940.0055555555555555566/37333 380168.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/10?format=asciiX-rayInfrareddefaultJ/ApJS/194/10/table1Near-infrared magnitudes for the 7472 Chandra X-ray sources in the area of the HAWK-I mosaicrecnoRecord number assigned by the VizieR team.
